Description:
------------
When dealing with MySQL STORED PROCEDURES it's often necessary to set 
flags as a parameter for mysql_connect which are not (yet?) defined in 
the current versions:

CLIENT_MULTI_STATEMENT (65536) and
CLIENT_MULTI_RESULTS (131072)

Otherwise the application will return a "PROCEDURE xxx can't return a 
result set in the given context" error, even if a CALL from phpMyAdmin 
or any other client is working without problems.


Reproduce code:
---------------
  mysql_connect ($host, $user, $pw, $newlink);
  mysql_unbuffered_query ('CALL myproc()');

won't work, but

  mysql_connect ($host, $user, $pw, $newlink, 131072)
  mysql_unbuffered_query ('CALL myproc()');

will work just as expected.
